Hydrogen Fuel From Solar Nanoforests

Hydrogen Fuel From Solar Nanoforests

Hydrogen Fuel From Solar Nanoforests 03/14/2012 from SustainableBusiness.com Engineers at University of California, San Diego are creating a “nanoforest” that can capture solar energy and use it generate fuel from hydrogen. Running cars, homes and buildings on hydrogen has long thought to be the ultimate clean solution, but getting there has been tough. They say the tiny nanowire trees, made from abundant sources like silicon and zinc oxide, mimic the way trees naturally absorb energy from the sun through photosynthesis. Using these inexpensive materials could be a key to mainstreaming hydrogen fuels. Until now, hydrogen fuel cells have depended on platinum, an expensive catalyst. And they’ve also depended on electricity to separate hydrogen from water, usually from fossil fuels. 3D vertical nanotrees capture much more sunlight than do flat surfaces, which simply reflect i...
